siding atColumbus, in the county of Frank- 1i?! State of'Ohio,'haveinvented certain new and useful Improvements in Feed-Gages forPrinting-Presses, of which thefollow- 'ing is a specification. Y

he present invention relates to an improved. feed gage or gage pin, foruse in connection with platen printing presses, wherein the tympan sheetis employed on the platen of the press and the gage pin is inserted orsecured in the sheet, to facilitate the feeding'of the sheetsto' beprinted to the press and regulate "and maintain the proper positionofthe sheets to be printed as they are presented to the type. 1 g

r The pIiIIIEtIYfibjBCt0f the invention'is to improvethe construction ofthe devices of this character in certain particulars of construction, torender the device more durable and better braced when pinned o'r securedto the tympan sheet by the prong entered therein to render niore' stablethe-adj ustable slide tongue so that it will remain in its fixedpositionwithout likelihood of disarrangement and; to so construct the gage headas to prevent the tongue being moved to such position as to endanger thetension feet, durin the action of the platen, and to this end 1: einvention resides in certain novel combinations and arrangeiiients ofparts as hereinafter 'more specifically described and laiinedq' thea'ccornpanying drawingsone complete example of the physical emiidiinentof the invention is illustrated, and in addition, a modified form" ofthe invention is depicted, shoWin the best modes I have so far devisedfor t e practical application, of the principles of the invention.

Figure 1 is a plan view showing a portion of the platen of the presswith the tympan sheet and the feed gage secured thereto, the corner of asheet to be printed also bein shown.

Fig. 2 1s a side or edge view of the gage, detached.

Fig. 3 is a plan view of the gage. Fig. 4 is a sectional view of thegage on line 1-1 of Fig. 3.

Fig. 5 is an enlarged view of a part of the blank from which the gagehead, shanks and tongue are folded.

illustrate the applicatidn thereto or the gage which is secured bypassing the"sharpened end of the pron i through the tyrnpan sheet usual;to" old"theg'ag eiii position.

' Sheet inet'alfa'snsual-is efmpl yed in the construction of the twoineinbersof the giage,

lead indicated as a holeby numeral 5, which has a vertical fwali iirwall pcrpen' dicular thereto indicated at 6 forming "the 5.152155%,forthe sheets ii. 1T hef'gac has lateral wingsl, 7, folded back at eac"side thereof, and four teeth" 8, 8 and 8' 8 are inshioned on thewallfiand the wings} i'espectively, the first pair 7 of teeth beingarranged transversely,ofthe ga and these'coiid: pair being locatedlongitur inally thereof, so that they maybe embedded'inthe tynipan sheetin such manner'astoprovide the best longitudinal bracing of the gage aswell as the best transverse bracing of the gage,because of the fact thatthe longitudinalaxes of the teeth, in pairs, are arranged at rightangles.

Thus between'the prong 4 and the two pairs of teeththe gage is Heldfirmly in position, and the separation of the'teeth ,8" ends froxn thepoint of engagenient'o f the prong with the tympan sheet permits theutilize; 'tion of niorehiaterial therebetwen so that the paper sheet isless ,lilgel to tear or 'ln th i s inanner the ounces of the =I i- EE'gage becoming loosened or turned are elimfingers are designed to liealong each side of the point of the prong and press down on the outersurface of the tyinpan sheet where the prong projects through, to addfirmness and stability to the bracing of the e. he adjustable slidetongue 11 projects from its bodyporticn 12, which is formed with the proections or resser feet or ten sion feet 13, 13, frictionall'y engagingand slidable on theshanks 9 9, and at 14, H lateral guide flanges areprovided on the body. of the ton he to slide along the edges of theshanks w l enithetongue is being adjust-ed, and to retain the tongue inproper p' iti j The tongue projects through the slot 15 in the end wallof the gage head and this oint is fashioned with sharp corrugationsorming rack teeth 16 that are engaged by the rib 17 stamped through thematerial of the gage head 5 and rejecting from the underside or thehead.'lhe wall 15f of the slot, 15 also engages these rack teeth, the walland rib being adjusted with relation 'to the teeth so that the willengagecompleiiientary teeth, and t e resiliency of the material of whichthe tongue is made tends to hold the tongue in contact with the walledge .15 and the rib, so that the tongue ma be adjusted to properposition and wil there beheld firmly fixed, as desired. A shoulder. 18on the tongue co-acts with a shoulder 19 on he head at one end of theshanks 9 to orn1 a stop to prevent the tension feet 13 being pushed overthe head of the gage and becoming injured by the action of the pressinanwho often has occasion to tap the head gentlyto seat or enihed the teeth8 8 8' 8 in the tympan sheet.

The rear ends of thefsha nks are notched at 2020 to accommodate theflanges 14 of the tongue body when the parts arebeing assembled, andafter the tongue is passed through the slot 15 the bodyof the tongueslides on the shanks to proper position.

iVhat I claim iS l. A feed gage comprising a slotted head having arearwardly projecting prong and rearwardly projecting spaced shanks, atongue having its forward free end projecting through the slot of thehead and its rear end movable in the space between said shanks, saidrear end of said tongue having a laterally enlarged body overlying theshanks and provided with extension feet projecting longitudinally alongthe upper surfaces of said shanks.

'2. A feed gage comprising a slotted head having a rearwardly projectingprong and rearwardly projecting spaced shanks, a tongue having itsforward free end projecting through the slot of the head and its rearend movable in the space between said shanks, said rear end of saidtongue having a laterally enlarged body overlying the shanks andprovided with extension feet projecting longitudinally along the uppersurfaces of said shanks, said ton e also having a vertical shoulderedportion forwardly of its said enlarged body to engage the said head atthe forward end of the shanks.

3. A feed gage of the character described, comprising a transverselyslotted gage head, having a shoulder, a transverse rib, and providedwith a lengthwise prong, lon gitudinally extending shanks, a lengthwiseadjustable tongue, having side flanges provided with tension feetengaging the shanks of the head, said tongue having a corrugated portioncooperating with the rib and with the head at one side of its slot anda. shoulder formed on the tongue engngeable with the head for thepurpose described.

4. A feed gage comprising a slotted head having rearwardly projectingshanks and a tongue engaging portion forwardly of said shank, a lenthwise prong, and a corru ated tongue working through the slot andhaving a rear portion slidably engaging the shanks and provided withupper tension feet engaging the upper surface of the shanks to hold itscorrugated portion upwardly against the tongue engaging portion of thehead.

In testimony whereof I afiix my signature.
